What was your experience in healing plantar faciitis?

A number of years ago, I developed painful plantar faciitis in my right foot. I did not know what it was until a doctor told me. I had to cease powerwalking for more than a year.

This past May, I began to develop identical pain in my left foot. I immediately stopped powerwalking in order to help it heal. I began easing into powerwalking 2 weeks ago. I started with short distances. I went my former 2.4 miles on Wednesday morning, and my foot ached all day afterward. Needless to say, I will be taking some days off to rest it, and when I resume, I will go a shorter distance.

When you had plantar faciitis, what helped to heal it? Did you do anything to speed the recovery?
